About Us
Built in a Shed. Ridden Worldwide.
Radical Bicycle Co is a rider-owned mountain bike brand based in Shropshire, UK — founded on the principle that fast, fun, beautifully built bikes shouldn’t come with corporate fluff or five layers of marketing speak.
We started small. Like, actual shed small. What began as a back-garden welding project has grown into a globally recognised name — known for pushing design limits, building bombproof bikes, and doing it all with a healthy dose of sarcasm and trail dust.
At the heart of Radical is a deep love for mountain biking in all its forms — from wild natural descents to DIY jump lines and chaotic race weekends. We specialise in handcrafted steel and titanium hardtail frames, made in small batches (or one-offs if you’re after something truly bespoke). Every frame is designed, tested, and built with performance and personality in mind — and no compromises in sight.
What makes us different?
We keep things raw, real, and rider-focused. Our made-to-order process gives you the kind of customer experience you’d expect from the motor industry — think build updates, realistic timelines, and actual communication. It’s service with a soul, and bikes with backbone.
We might not have a massive team or fancy boardrooms, but what we do have is a relentless work ethic, an obsession with good geometry, and a growing global crew of riders who get what Radical is all about.
Meet the Man Behind the Mayhem
Radical is the brainchild of Kieran Crosbie — ex-Forces, lifelong bike nerd, and someone who’s just as comfortable designing bikes as he is on a race stage. With years of experience managing the design, supply, and installation of bespoke steel and aluminium projects across the UK, Kieran brought that technical knowledge and no-nonsense work ethic straight into the bike world.
He’s raced enduro, toured the world (in camo, not lycra), and now channels that passion into building frames that can take a beating and keep begging for more. Radical isn’t just a brand — it’s a personal mission to build bikes that are fun, fast, and a little bit feral.
We’d be remiss not to mention Steve — the welding wizard up the road who helps bring our UK-made frames to life. He’s been burning rods and his handiwork is a big part of why Radical frames ride as good as they look. It’s a team effort — just a very small, very stubborn team.
